This document discusses the evolution of 4G mobile technology, including its key features and capabilities. 4G provides ultra-broadband internet access to mobile devices using an entirely packet-switched network with wider bandwidths of 100 MHz or more. It allows for global mobility, customized personal networks, and multimedia applications at low transmission costs. While 4G enables benefits like high usability, support for multimedia services, and high bandwidth with tight security, it also faces challenges such as the need for complicated hardware, difficulty in implementation, higher battery usage, and greater expense compared to previous generations of mobile technology.

9. How 4G Works ?
• The IP address is based on IPv6.
• IPv4:
X.X.X.X
(32 bits)
example: 216.37.129.9
• IPv6:
4 × IPv4
(128 bits)
• example:
216.37.129.9 , 79.23.178.229 , 65.198.2.10 ,
192.168.5.120
